How do we know that wisdom comes from God?

According to James 3, wisdom that descends from above is notably different from earthly wisdom. The divine wisdom is 'first pure, then peaceable, gentle, easy to be entreated, full of mercy and good fruits, without partiality and without hypocrisy.' This wisdom produces characteristics that align with God's nature and leads to peace and reconciliation rather than confusion. In contrast, earthly wisdom is described as 'earthly, sensual, and devilish,' often resulting in strife and conflict. Thus, true wisdom is identifiable through its fruits and the harmony it fosters among believers.
